H4 Smoke Tri Fins

The H4 looks and surfs different to any other fin. Precision Swiss engineering matched with a highly evolved template provides an unprecedented level of control and predictability at high speeds.

UNIQUE TEMPLATE

Radically different side & center fin templates create a powerful fin set with ultimate speed & drive.

• Side Fin Profile: Lower section produces maximum acceleration, while hatchet like tip creates stability & control.
• Center Fin Profile: Highly raked elliptical outline reduces drag, and offers feeling of predictability when releasing through turns.
• Fin Foils Template: Thicker base with tapered tip optimizes flex & regulates the release of energy during rail to rail transitions.

Ideal Conditions

• A wide range of conditions, particularly good in critical overhead waves.

Board Types

• Designed to fit the FCS II Fin System.
• Recommended for performance shortboards with moderate-to-low rocker.

Fin Family

• Accelerator: Find Control. Speed, flow and response with added control.

NEW CONSTRUCTION

• Precision Swiss Engineered: Creates perfect synergy between fin geometry & HI-FI materials, giving smooth & predictable feel.
• High Density Uni-Directional Carbon Fibre: Light & super strong with custom orientation to transfer more of your energy into speed than any other fin.
• Dynamic Trailing Edge: Internal composite morphs under extreme load, enabling the fins to be pushed harder without sliding out.
• Innovative Production: Highly specialized robotic automation combined with camera assisted quality control, ensures absolute accuracy.
